Wireless Power Transfer for Electric Vehicles

Relatore:Prof. Mauro Feliziani, Università dell’Aquila.

Abstract:
This short course explores the emerging field of wireless power transfer (WPT) and how it could revolutionize road transportation through wireless charging of electric vehicles (EVs). The growth of electric mobility can mitigate the environmental problems caused by conventional internal combustion engine (ICE) vehicles, which are responsible for greenhouse gas (GHG) emissions. Conventional EV charging methods rely primarily on physical connections, such as plug-in chargers, to recharge the EV battery. These charging stations require users to physically park and plug in their vehicles. By enabling the wireless transfer of electricity, WPT offers a simpler, safer and more comfortable charging experience. Currently, WPT technology is almost ready to be applied to stationary EVs. However, extensive research is already underway to enable charging of electric vehicles while moving on electrified roads and lanes, using dynamic WPT technology. This advancement aims to eliminate problems related to the limited range of EVs and frequent stops to recharge. The development of the DWPT technology is of fundamental importance for the widespread adoption of autonomous driving systems, as it allows EVs to operate without any physical interaction from the user, achieving full autonomy and practically infinite range. This short course is a guide for PhD students and young researchers to understanding the principles, methodologies and applications of WPT for electric mobility.
